DiExSys Vision Zero Suite
Transportation engineers are beginning to understand that humans and computers working together make better decisions than either alone.
DiExSys Vision Zero Suite (VZS) is an HSM compliant safety management system that harnesses the power of predictive analytics and diagnostic pattern recognition to produce the augmented intelligence needed for effective road safety management, and to guide our clients on their journey toward a shared vison of zero traffic fatalities.
DiExSys VZS provides predictive, diagnostic and analysis tools which reveal the nature and magnitude of the safety problems on the network, segment and intersection levels. Its algorithms automatically correct for the regression to the mean bias using the empirical Bayes method.
VZS is capable of evaluating cost-effectiveness of safety improvement strategies, enabling network screening, producing observational before-and-after studies, leveraging GIS mapping, and recognizing infrastructure and behavioral patterns, facilitating implementation of countermeasure deployment and targeted enforcement.
The decision support analysis of safety problems provided by VZS is designed to follow the process of project scoping; additionally, it provides a platform for system-level planning and risk management. Its framework is flexible and allows matching the extent of safety improvements to the scope of the project. DiExSys VZS tools are designed to be highly intuitive and versatile, and are equally applicable for use in the office as well as during field visits.
DiExSys has developed augmented intelligence algorithms incorporated into VZS that, when combined with practical knowledge of transportation engineering, provide effective solutions with defensible data driven results.
Making the Most of Your Crash Data
Independent of its quality, your crash data is and will remain the best source of data for the effective safety management in your state, city or county.
From many years of experience with crash data management, we have learned that data quality varies across the country. If you have a data problem, it is likely that we have already solved one like it elsewhere. Over the years, DiExSys has successfully mitigated many forms of incomplete or missing data to provide effective safety decision support analysis for our clients.
We understand which data sources are most useful in understanding the nature of the safety problems and developing countermeasures. We will help you to be economical and discerning in selecting the data used for effective safety management. Perfection in data quality is not attainable, yet excellence in serving your safety data needs is well within our reach.
Improving Safety and Mobility
Safety and mobility are interrelated and cannot be well understood and managed in isolation. The DiExSys team is highly experienced in optimizing operations in concert with providing maximum safety when delivering innovative transportation solutions to our clients.
VZS now includes interactive facility-specific operational decision trees constructed to reflect operational reality and identify opportunities to improve safety and mobility on different facilities in urban and rural environments. DiExSys Safety-based Variable Speed Limit (VSL) algorithm has been developed to compute safe speeds in real time in response to changing levels of congestion and road conditions on freeway corridors.
Innovative and experienced
As pioneers in the science of road safety analytics, we are known for our breakthrough innovations.
Our principals and employees hold advanced degrees in engineering, applied mathematics, data science and geographic information systems. We bring many decades of experience working for Departments of Transportation, academia and private industry to our work at DiExSys.
Independent and conflict-free
The demand for transparency and ethics by the public today is on the rise. This aligns well with our focus on science-based data driven decision support analysis in safety management.
With a clear understanding of the nature and magnitude of safety problems, transportation professionals are well positioned to make informed, defensible and transparent decisions about how best to allocate resources to improve road safety.
